We all knew this. You are probably the only who did not. FYI, Shaymin and Regigigas are also rumored to have alternate forms but no pictures have been released.
I just wanna see the stats of those 3 >.<
Yeah, without Slow Start he will without a doubt become an uber, and I'd bet a good one at that. If it weren't for that ability he would be extremely kickass now.
I think that's likely, but I would bet that this Giratina can switch forms (like Deoxys) at the meteors in Veilstone.They will most likely work like 3rd gen Deoxys, switching between games.
the meteors only allow deoxys to change. They will probably make another little "area" where giratina can change between normal and origin.
